Matching seal (radial shaft seal)
8 × 24 × 7 mm
Seal weight: ≈ 5 g
Other common widths: 8 × 24 × 10 mm
The seal's inner diameter matches the shaft (8 mm) and its outer diameter matches the housing bore (24 mm); the width depends on the space in the housing. NBR (double lip, TC type) is recommended for general use and FKM (Viton) for high temperatures.
